Test of gross motor development-2 for Filipino children with intellectual disability: validity and reliability

This study aimed to examine aspects of validity and reliability of the Test of Gross Motor Development-2 (TGMD-2) in Filipino children with intellectual disability. Content and construct validity were verified, as well as inter-rater and intra-rater reliability. Two paediatric physiotherapists tested 81 children with intellectual disability (mean age = 9.29 ± 2.71 years) on locomotor and object control skills. Analysis of covariance, confirmatory factor analysis and analysis of variance were used to test validity, while Cronbach’s alpha, intra-class correlation coefficients (ICC) and Bland–Altman plots were used to examine reliability. Age was a significant predictor of locomotor and object control scores (P = 0.004). The data fit the hypothesised two-factor model with fit indices as follows: χ² = 33.525, DF = 34, P = 0.491, χ²/DF = 0.986. As hypothesised, gender was a significant predictor for object control skills (P = 0.038). Participants’ mean scores were significantly below mastery (locomotor, P < 0.001; object control, P < 0.001). Cronbach’s alpha was 0.830 for locomotor and 0.792 for object control components. ICC for locomotor and object control scores ranged from 0.995 to 0.998, suggesting excellent intra-rater and inter-rater reliability, confirmed by Bland–Altman analysis. This study provides evidence of sufficient content and construct validity, internal consistency and rater reliability of TGMD-2 for Filipino children with intellectual disability.     

The importance of cohesion and enjoyment for the fitness improvement of 8–10-year-old children participating in a team and individual sport school-based physical activity intervention

This study investigates the enjoyment and cohesion of school children participating in a school-based high-intensity physical activity (PA) intervention. Both enjoyment and cohesion have been found to be important factors for adherence to regular physical and sport activity, an important outcome of PA interventions. The sample consisted of 300 pupils (mean age: 9.3 years; 52.7% female) assigned to a team sport intervention, an individual sport intervention, or a control group for 10 months. The Physical Activity Enjoyment Scale and Youth Sport Environment Questionnaire were used to measure enjoyment and cohesion. The Yo-Yo IR1C test determined fitness improvements. Results showed that enjoyment and cohesion (social) measured at the beginning of the intervention significantly predict fitness improvements achieved after 10 months. No differing developmental effects over time could be found in the intervention groups with regard to cohesion and enjoyment when comparing them to the control group. However, enjoyment and cohesion (social) significantly decreased in the groups that performed individual sports. Team sports seem to be more advantageous for the development of enjoyment and cohesion, which are both factors that positively impact the health outcomes of the intervention.     

Co-authorship networks in the digital library research community

The field of digital libraries (DLs) coalesced in 1994: the first digital library conferences were held that year, awareness of the World Wide Web was accelerating, and the National Science Foundation awarded $24 Million (US) for the Digital Library Initiative (DLI). In this paper we examine the state of the DL domain after a decade of activity by applying social network analysis to the co-authorship network of the past ACM, IEEE, and joint ACM/IEEE digital library conferences. We base our analysis on a common binary undirectional network model to represent the co-authorship network, and from it we extract several established network measures. We also introduce a weighted directional network model to represent the co-authorship network, for which we define AuthorRank as an indicator of the impact of an individual author in the network. The results are validated against conference program committee members in the same period. The results show clear advantages of PageRank and AuthorRank over degree, closeness and betweenness centrality metrics. We also investigate the amount and nature of international participation in Joint Conference on Digital Libraries (JCDL).     

Why Should States Fund Denominational Schools?

It is generally accepted that liberal states should fund public schools for compulsory education. But whether states should also finance denominational schools is controversial. Does such funding not compromise the principle of liberal neutrality? In this article we evaluate two opposing views on this question. Both views give different interpretations of liberal neutrality and both have contrasting views on the relation between education and conceptions of the good. Arguing that neither view is convincing, we defend an alternative view, which holds that the liberal state under certain conditions should fund denominational schools.     

Using micro-mechanical modelling to predict short-fibre composite properties in computer-aided design of sporting equipment

Computer-aided design (CAD) of sporting equipment requires knowledge of the mechanical properties of proposed materials. The mechanical properties of composite materials are often not as simple to obtain as those of conventional materials, in which case micro-mechanical modelling could be used in conjunction with CAD software. A micro-mechanical model was used to predict the flexural modulus of composite materials, based on the assumption of partial interfacial adhesion between composite components. It was found that the partial adhesion model was both practical and consistently accurate. The partial adhesion model accounted for adhesion between components by considering an ‘effective shear value’ at the interface. The model was compared to experimental data for glass, wood and carbon-fibre reinforced polyethylene. It was shown that the adhesion coefficient ranged between 0.1 for carbon fibre, 0.5 for glass fibre and 0.8 for the wood fibre composites. It was shown that using micro-mechanical modelling to predict composite mechanical properties, as opposed to simulating the comprehensive composites structure, computer processing time and file size can be reduced with little compromise in simulation accuracy.     

Prediction of adult height in girls: the Beunen-Malina-Freitas method

The purpose of this study was to validate and cross-validate the Beunen-Malina-Freitas method for non-invasive prediction of adult height in girls. A sample of 420 girls aged 10-15 years from the Madeira Growth Study were measured at yearly intervals and then 8 years later. Anthropometric dimensions (lengths, breadths, circumferences, and skinfolds) were measured; skeletal age was assessed using the Tanner-Whitehouse 3 method and menarcheal status (present or absent) was recorded. Adult height was measured and predicted using stepwise, forward, and maximum R (2) regression techniques. Multiple correlations, mean differences, standard errors of prediction, and error boundaries were calculated. A sample of the Leuven Longitudinal Twin Study was used to cross-validate the regressions. Age-specific coefficients of determination (R (2)) between predicted and measured adult height varied between 0.57 and 0.96, while standard errors of prediction varied between 1.1 and 3.9 cm. The cross-validation confirmed the validity of the Beunen-Malina-Freitas method in girls aged 12-15 years, but at lower ages the cross-validation was less consistent. We conclude that the Beunen-Malina-Freitas method is valid for the prediction of adult height in girls aged 12-15 years. It is applicable to European populations or populations of European ancestry.     

Technological pedagogical content knowledge in teacher education: in search of a new curriculum

The aim of this study was to explore the ways in which teacher education institutions (TEI) prepare pre-service teachers for integrating information and communication technology (ICT) in their classroom practise. Specifically, a multiple case study was conducted to examine the ways in which the development of technological pedagogical content knowledge (TPACK) was promoted in the existing curriculum of three TEI in Flanders. In the three cases, data were drawn from semi-structured interviews with the heads of the department and the ICT coordinators. Focus group discussions collected the perspectives of pre-service teachers and teacher educators. The results indicate that (1) the three institutions are moving from ICT as a ‘stand-alone’ course towards embedding ICT across the curriculum and (2) three approaches were adopted for developing pre-service teachers’ TPACK, each representing different ways of understanding the place of ICT in the curriculum. The discussion will focus on the challenges and opportunities inherent in understanding how to develop pre-service teachers’ TPACK in the curriculum of TEI.     

Recognising and exploring action-theories: A reflection-in-action approach to facilitating experiential learning

Abstract

Outdoor education has typically presented itself as a specific approach to experiential learning. This article proposes that experiential learning can be understood as a process in which learners recognise and develop their action-theory and that the aim of outdoor development programs — whether in mainstream education, corporate training or therapy — is to facilitate this process. After introducing the notion of action-theory, I will present a particular approach to facilitation, which can be understood as a reflection-in-action approach. I conclude by situating this approach in the wider range of facilitation models in the literature on outdoor education and adventure therapy.     

Knowledge production from an African perspective: International information flows and intellectual property⋆

This paper investigates current trends in knowledge production and the impact that they have on the international flow of information. Three directions of information flow (North–South, South–North and South–South) are investigated from an African perspective. A moral rather than a legal view is taken of intellectual property. The authors’ concern is that the balance between the public good and private interests has been disturbed. It is premised that there are general moral principles that can serve as a basis for decisions on North–South, South–North and South–South information flows. Three ethical pillars serve as a basis for reflection on current information flows. These are: social justice, human rights, and the concept of the common good. Current developments in scholarly publishing and intellectual property rights that affect the North–South information flow are examined, and responses to the growing imbalance between rights holders and authors, such as the open access movement, are considered. These developments also affect South–North information flows, where both exploitation and neglect of Africa's knowledge resources need to be countered. Lastly, South–South information flows between African countries are considered.
